IMPROVEMENT IN THIMBLES.

Specification forming part of Letters Patent No. 138,445, dated April29, 1873; application filed February 17, 1873.

To all whom it may concern:

Be it known that I, WILLIAM P. SLENsBY, of the city, county, and Stateof New York, have invented an Improved N eedle-Threadin g Thimble, ofwhich the following is a specification:

This invention relates to a new combination of thimble andneedle-threader, when the latter is cast in one piece and provided withprojecting rivets or pins, whereby it is attached to the thimble, andwhereby the spring which is to retain the needle in the threader is alsoattached to the latter. The invention consists, first, in thecombination of the cast B needle-threader with three projecting pins, ofwhich two at one side serve to fasten the threader to the thimble, andone at the other side to hold the tension-spring in place. The inventionalso consists in perforating the thimble for the reception of the rivetson the threader.

By this manner of construction the connection of the two parts named isgreatly simpli-. fied, and a firmer hold obtained than by the ordinaryprocess of soldering.

In the accompanying drawing, Figure 1 represents a perspective view,showing the three parts-to wit: the thimble, the'threader, and thespring-detached. Fig. 2 is a longitudinal section of the threader,showing it applied to a thimble.

holds the needle in position in the threader, the said spring with itsyielding end constituting part of one side of the needle-receptacle a,which is clearly shown in Fig. 2.

The spring 0 is attached to the threader B by means of a rivet, 6,formed on the latter. ff are two more rivets or projecting pins formedon the casting B for the purpose of fastening the same to the thimble A.The thimble is perforated, as at g g, for the reception of these pins ff, and has its rim or lower flange it cut out in line with" theseapertures for accommodating the body of the threader By reference toFig. 1 it will be observed that the pin 6 is on that face of thethreader B which stands at right angles to that face of the same fromwhich the pins f project.

For connecting the parts the spring 0 is I first riveted to the threaderB by means of the pin 6, and the combined threader and spring are thenriveted to the thimble, in the position indicated in Fig. 2, by fittingthe pins f through the apertures g, and then upsetting or heading themwithin the thimble to secure the threader in place.

Claims.

l. The threader'B, cast with projecting rivets e and ff, substantiallyas herein shown and described.

2. The thimble A, perforated as shown at g g, substantially as and forthe purpose specified.

3. The combination of the perforated thimble A with the cast threader Bhaving the pins eff, and with the spring 0, all arranged for connectionwith each other in manner set forth.
